void A(){} int变量 x int x;x=A();就会出现
Object is the universal data type in the .NET Framework, so every type derives from Object.Because the compiler considers this conversion to be already defined, it does not allow you to redefine it.Error ID: BC33028To correct this errorRemove this operator definition entirely. It is already...
这一句，malloc返回的是void*，要强制转换成需要的类型，改成 p = (int(*)[2])malloc( N*sizeof(int [2]) ) ;如果你原型是void exchange (int *a[81], int n)那么需要exchange (&a,10);

error C2440: 'static_cast' : cannot convert from 'void (__thiscall CChatDlg::* )(WPARAM,LPARAM)' to 百度是较快解决问题的方法 你这个问题应该是VC6项目迁移向高版本时发生的,VC6后消息的检查更为严格,以前在VC6下完全正常运行的消息映射在其它版本下编译不通过。
类型不匹配:不能把空转换成字符串类型 你检查一下，是不是你调用的方法返回为空，但是在你调用的时候你将这个方法的返回值赋给了一个String类型的变量

你的函数要求返回一个整型 你可能使用的是 return;修改成 return 0;等int类型即可。你
